GENERAL INFORMATION 
Dual IlG will control many annual grasses and certain broadleaf weeds in' 
com (all types), peanuts, potatoes, and soybeans. It should be applied 
prior to the emergence of weeds. It may be preplant surface-applied 
(com and soybeans only), or incorporated into the surface 1-2 inches of 
soil before planting, or left on the soil surface during or after planting. Dry 
weather following an application of DualllG may reduce its effectiveness. 
Shallow cultivate if weeds develop or if tillage is necessary to improve the 
physicc:1 condition of the soil. 
Precaution: Injury may occur to crops other than corn following the use of 
DualllG under abnormaliy high soil moisture conditions during early 
development of the crop. 
Do not apply under conditions which favor runoff or wind erosion of soil 
containing this product to non-target areas. 
To prevent off-site movement due to runoff or wind erosion, 
1. Avoid treating powdery dry or light sand soils when conditions are 
favorable for wind erosion. Under these conditions, the soil surface 
should first be settled by rainfall or irrigation. 
2. Do not apply to impervious substrates such as paved or highly 
compacted surfaces. 
3. Do not' use tailwater from the first flood or furrow irrigation of treated 
fields to treat non-target crops unless at least '12 inch of rainfall has 
occurred between application and the first irrigation. 
Soil Textures and Herbicide Rates 
Where rates are based on coarse-, medium-, or fine-textured soils, it is 
understood that soil textural classes are generally categorized as follows: 
Coarse 
Sand 
Loamy sand 
Sandy loam 
Medium

Weeds Partially Controlled*: common purslane, eclipta, Florida 
beggarweed", hairy nightshade, sandbur, seedling johnsongrass, 
shattercane, volunteer sorghum, wild proso millet, and woolly cupgrass. 
'Control of these weeds can be erratic due partially to variable 
weather conditions. Control may be improved by following these 
suggested procedures: 
1. Thoroughly till moist soil to destroy germinating and 
emerged weeds. If Dual IIG is to be applied preplant 
incorporated, this tillage may be used to incorporate Dual IIG if 
uniform 2-inch incorporation is achieved as recommended 
under Application Procedures. 
2. Plant crop into moist soil immediately after tillage. If Dual IlG 
is to be used preemergence, apply at planting or immediately 
after planting. 
3. If available, sprinkler irrigate within 2 days after application. 
Apply 1/2-1 inch of water. Use lower water volume (112 \1']99) ,on 
coarse-textured soils and higher volume (1 inch) on fi.:Je-tex-
tured soils. ' , , , , , , ,

4. If irrigation is not possible and rain does not occur wiU,(~ A ' 
days after planting and application, weed control may be 
decreased. Under these conditions, a uniform, shallow cultiva­
tion is recommended as soon as weeds emerge.

5. In com, use 12-15 IbsJA or. the preplant surface-applied rates 
for Dual JIG alone or sequentially, if allowed, when making 
preplant incorporated or preemergenceapplications. 
"For partial control of this weed, use a minimum of 8 IbsJA and 
apply preemergence. 
Application Timing 
Preplant Surface-Applied: For minimum-tillage or no-tillage systems 
only. Dual JIG alone may be applied up to 45 days before planting certain 
crops. Use only split applications for treatments made 30-45 days before 
planting, with 2/s of the recommended broadcast rate for the crop and soil 
texture applied initially and the remaining lis at planting. Treatments less 
than 30 days before planting may be made as either a split or a single 
application. If weeds are present at the time of treatment, apply a labeled 
contact herbicide (for example, Gramoxone® Extra or Roundup®). 
Observe directions for use, precautions, and restrictions on the label of 
the contact herbicide. To the extent possible, do not move treated soil out 
of the row or move untreated soil to the surface during planting, or weed 
control will be diminished. 
Preplant Incorporated: Apply Dual IIG to the soil and incorporate into 
the top 2 inches of soil within 14 days before planting, using a finishing 
disk, harrow, rolling cultivator, or similar implement capable of providing 
uniform 2-inch incorporation. Use a preplant incorporated application if 
furrow irrigation is used or when a period of dry weather after application 
is expected. If crop will be planted on beds, apply and incorporate Dual 
fiG after bed formation, unless specifieq otherwise. 
Preemergence: Apply Dual IIG during planting (behind the planter) or 
after planting. but before weeds or crops emerge. 
Fall Application (Only in lA, MN, ND, SD, WI, and portions of NE and 
IL - See specific instructions in the Corn and Soybean sections of 
this label for timing of application and other information): Do not 
apply to frozen ground. Use on medium and fine soils with greater than 
2.5% organiC matter that will be planted to com or soybeans the next 
spring. Ground may be tilled before or after application. Do not exceed a 
2 to 3-inch incorporation depth if tilled after treatment. Note: If a spring 
application is made, the total rate of the fal! plus spring applications must' 
not exceed the maximum total rate for the specific crop, or illegal 
residues may result.

Application Procedures 
• > 
Dual IIG may be applied either broadcast or banded. Do not aJ:'P!Y' ~ual 
IIG during periods of high winds. Wind may disrupt placement of tile 
granules and reduce weed control. Locate granular diffusers as close to 
the ground as possible. Windshield attachments are advisable.

Pneumatic (Compressed Air) Broadcast Application (Dual IIG 
Alone): Dual IIG may be applied through pneumatic dry fertilizer applica­
tors which are equipped with special on-board herbicide metering bins. 
These metering units must be properly calibrated with Dual JIG prior to 
use. The placement of the granules in the applicator's distribution system 
should be designed to minimize segregation of the granules from the dry 
fertilizer materials. 
Precaution: DualllG should never be blended with other pesticide formu­
lations for application through on-board metering bins. Dual IIG should 
never be blender-mixed with liquid or dry fertilizer materials for broadcast 
pneumatic application. 
Broadcast Application ("Cyclone" or "Spinner"Type Spreaders): 
Dual JIG may be applied with a broadcast type (spinner) granular applica­
tor or with a cyclone type spreader. Use applicators and techniques that 
will apply the granules uniformly to the soil. Do not blend Dual JIG with 
other pesticides or fertilizers. Always calibrate the device with Dual JIG 
prior to use. 
Variable-Rate Broadcast Ground Application for Corn and Soybeans: 
Variable-rate technologies may be used for more precise applications. 
Two additive factors have been determined for use in application using 
variable-rate technologies. One of these factors (A) is directly related to 
soil texture and the other (8) is related to percent organic matter (OM) 
and soil texture. When these two factors are added together, the result­
ing application rate will be more precise for a soil of a given soil texture 
and organic matter content. Use the formulas below to assure a more 
precise rate for any given area within a field. 
Formulas* for Preplant Surface-Applied, Preplant Incorporated, 
Preemergence, and Early Preplant Applications - Refer to specific 
instructions regarding these applications in the Application Procedures 
section of this label, as well as the appropriate crop section.

Band Treatment: Dual JIG may be applied with any standard granular 
applicator capable of uniformly distributing a predetermined amount of 
granules to a desired area. Band treatment made at seeding should only 
be applied behind the press wheel. 
Note: Caution should be taken with seeding equipment so that any track 
(soil depression) made by the planter press wheel is minimal. This will 
reduce concentration of granules in the press wheel track by heavy rain 
which can result in crop injury. Soil tillage should not follow the use of 
band applications, unless<it is adapted so as not to displace the band and 
hence, reduce weed control in the band. In reduced tillage systems, 
injury may occur if the planter slit is not properly closed during planting. 
Applicator settings are given for band applications in Chart 1. These set­
tings were determined under laboratory conditions to ±5% accuracy. Note 
that the settings may differ depending on speed of application, as well as 
rate per acre. It is important that the user calibrate each individual 
granular applicator before its use. Since the actual setting for each 
individual granular applicator may vary, the settings shown should 
serve only as guidelines for calibration. 
Calculate the amount of Dual JIG needed for band treatment as follows: 
Band width in inches x Broadcast rate 
Row spacing in inches per acre 
= Band rate per 
acre 
Example: If 15 Ibs.!A is recommended for broadcast application and you 
wish to treat a band 14 inches wide in crop rows spaced 30 inches apart: 
14/30 x 15 7.0 Ibs. of granules needed 
for each acre that is to 
be treated

Calibration of Band Applicators 
To calibrate a granular applicator for a standard 14-inch band, a sample 
has to be collected while the applicator is either running or simulating a 
run over a distance of 500 ft. 
Procedure 
1. Fill applicator box with DuaillG. 
2. Reter to Chart 1 and adjust the setting on your applicator to corre­
spond to the desired rate per acre. 
3. Attach a plastic bag or similar container to the applicator spout after 
detaching the delivery tube. 
4. Make the SOD-ft. run at planting speed. 
Speedmme required to cover 500 ft.: 
4 mph = 1 min. 25 sec. 
5 mph = 1 min. 8 sec. 
6 mph = 57 sec. 
5. Weigh granules collected (or measure volume) and, if necessary, 
adjust and make successive runs until the setting delivers the cor­
rect number of oz. per 500 ft. of row, as shown in Chart 2. 
6. Repeat this procedure for each granular applicator box.

For control of annual grasses and broadleaf weeds listed under the 
General Information section, apply Dual IIG either preplan! surface, 
preplant incorporated, or preemergence to com before weeds emerge. 
For extended control of annual weeds, Dual IIG may be applied to weed­
free soil at the time of the last cultivation (lay-by application) as either a 
surface or shallow incorporated treatment. Follow instructions for use of 
DualllG under Application Timing. 
Preplant Surface-Applied 
A. Fall Application: 
1. Apply after September 30 in NO, SO, MN, WI, and north of 
Route 30 in IA. 
2. Apply after October 15 north of Route 91 in NE and south of 
Route 30 in IA. 
3. Apply after October 31 north of Route 136 in IL. 
In all locations, apply to crop stubble after harvest when the sus-
tained soil temperature at a 4-inch depth is less than 55°F and 
falling. In minimum-till or no-tillage systems on soils having greater 
than 2.5% organiC matter, use 10-151bs.lA on medium-textured 
soils and 12-15 Ibs.lA on fine-textured soils. Do not apply to frozen 
ground. A tillage operation may precede the application. A fall andior ,", 
a spring tillage may follow application, but do not exceed an incor- '""

as a split or as a single treatment. Apply 8 Ibs.!A on coarse soils not 
more than 2 weeks before planting. If weeds are present at the time 
of treatment, apply a labeled contact herbicide (for example, 
Gramoxone Extra or Roundup). Observe the directions for use, pre­
cautions, and restrictions on the label of the contact herbicide. To 
the extent possible, do not move treated soil out of the row or move 
un~reated soil to the surface during planting, or weed control will be 
diminished. To avoid reduced weed control, do not apply to frozen 
soil as rainfall may change the pattem of the Dual IIG granules. 
Injury may occur from movement of Dual IIG into the planter slit if 
the slit is not properly closed during planting. . 
C. On medium- and fine-textured soits with minimum- or no-tillage sys­
tems in CT, DE, MA, MD, ME, MI, NH, NY, OH, PA, RI, VA, VT, and 
WV, preplant surface applications may be applied following the 
directions for use above. If the amount of rainfall results in unsatis­
factory length of weed control following the earlier treatment, a 
postemergence application of an appropriately labeled broadleaf 
and/or grass weed herbicide could be used, i.e., AAtreX®, Beacon®, 
Bicep®, Exceed®, Accent®, Banvel®, Basagran®, bromoxynil 
(Brominal® or Buctril®), or 2,4-0. Observe all directions for use, 
precautions, and limitations on the label of the postemergence her­
bicide. 
Preplant Incorporated: Using the appropriate rate from Table 1, broad­
cast DualllG to the soil and incorporate within the surface 1-2 inches of 
soil within 14 days before planting, using appropriate surface incorporat­
ing equipment, such as a finishing disk, harrow, rolling cultivator, or simi­
lar implement capable of providing uniform incorporation. 
Preemergence: Band or broadcast Dual JIG to the soil surface during or 
after planting and before weeds emerge, using the appropriate rate from 
Table 1. For band treatment, apply granules behind the press wheel. In 
reduced tillage systems, injury may occur from movement of DualliG into 
the planter slit if the slit is not properly closed during planting.

should not bring untreated soil to the surface. Postplant incorporated 
application may be made any time after planting to drag-off, but before 
potato emergence. Incorporate, using an implement that distributes Dual 
IIG within the top 1-2 inches of soil. Do not damage potato seed pieces 
or sprouts with incorporation equipment. 
Preemergence: Apply DualllG at 6-12 IbsJA, either after planting as a 
preemergence, delayed preemergence, after drag-off or hilling treatment, 
but before weeds emerge. Up to 15 Ibs.!A of DualllG alone may be used 
where soil organic matter is between 6% and 20%. 
Precautions: (1) Do not use on muck or peat soils. (2) If cool, wet soil 
conditions occur after application, DualllG may delay maturity andlor 
reduce yield of Superior and other early maturing potato varieties. To 
avoid crop injury, (3) Do not use on sweet potatoes or yams. (4) Do not 
apply both preemergence and incorporated treatments, and (5) Do not 
use in Kern County, CA. 
Note: To avoid illegal residues, potatoes treated with Dual IIG should not 
be harvested within 60 days after the at-planting to drag-off application. 
Rotational Crops 
Do not rotate to food or feed crops other than those listed below. 
(1) If crop treated with Dual IIG is lost, any crop on this label may be 
replanted immediately. Do not make a second broadcast application of 
Dual IIG. If the original application was banded and the second crop is 
planted in the untreated row middles, a second banded treatment may be 
applied. (2) Barley, oats, rye, or wheat may be planted 41/z months follow­
ing application; alfalfa may be planted 4 months following application. 
(3) Any crop on this label in addition to cotton, cabbage, peppers, pod 
crops, safflowers, grain sorghum*, root crops, tobacco, barley, buck­
wheat, milo, oats, rice, rye, and wheat may be planted in the spring 
following treatment. Clover may be seeded 9 months following applica­
tion. Do not graze or feed forage or fodder from cotton to livestock.

Environmental Hazards 
Cover or incorporate granules that are spilled during loading or are visible 
on soil surface in tum areas. Do not apply directly to water, to areas 
where surface water is present, or to intertidal areas below the mean 
high water mark. Do not contaminate water when disposing of equipment 
wash waters or rinsate. 
Ground Water Advisory 
This chemical is known to leach through soil into ground water under 
certain conditions as a result of agricultural use. Use of this chemical in 
areas where soils are permeable, particularly where the water table is 
shallow, may result in ground water contamination. 
Surface Water Advisory 
Metolachlor can contaminate surface water through ground spray drift. 
Under some conditions, metolachlor may also have a high potential for 
runoff into surface water (primarily via dissolution in runoff water), for 
several months post-application. These include poorly draining or wet
